Installing Halcyonic

March 1, 2026

Halcyonic is a calm business landing page — logo-and-nav header, two-column banner with a large CTA, and a four-up bordered feature grid. You want that shell running against real Dune content, not a static HTML5 UP unzip sitting next to it.

From JSR (recommended)

dune theme:install jsr:@dune/theme-halcyonic@1.0.1 --activate

Pins an exact version in the site import map. After install, dune lockfile:sync picks up the change, so the vendored static/html5up/ CSS, banner image, feature thumbnails, and webfonts ship with the package — no hand-copying files into themes/halcyonic/.

From a ZIP

Grab halcyonic-1.0.1.zip from dune-themes releases, extract into themes/halcyonic/, then set:

# site.yaml
theme:
  name: halcyonic

Either path installs the same package. Prefer JSR when you want theme updates without re-downloading ZIPs by hand.
